 the Anemone, the Anemone in no instance without the 

 Crab. Examples, indeed, do now and then occur, as

 the Crab, and induced it suddenly to vacate the shell 

 and desert its friend. The Bernard is never attended 

 by any such companion. 1 



The history of the tenancy of univalve shells by these 

 curious Crabs is well known ; and the comic scenes 

 that take place in the process of flitting from one tene- 

 ment to another, larger and more commodious, have been 

 so fully narrated by myself and other observers, that I 

 shall assume the reader to be conversant with them. 2

 full-grown Pagurus Prideauxii tenanting a whelk-shell, which carries a fine 

 specimen of the Cloak Anemone (Adamsia palliata). In the distance is 

 seen P. Bernhardus, inhabiting a shell of Natica.
